Question

我正在使用带有嵌入式Tomcat的Spring Boot并尝试使用JNDI，但收到以下错误：

javax.naming.NameNotFoundException：Name [jdbc / dataSource]

任何提示将不胜感激。

这是我的代码：

@Configuration
public class TomcatJndiConfiguration{

@Value("${database.driver}")
private String driverClassName;

@Value("${database.url}")
private String databaseUrl;

@Value("${database.username}")
private String databaseUsername;

@Value("${database.password}")
private String databasePassword;

@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
    return new TomcatEmbeddedServletContainerFactory() {

        @Override
        protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
                Tomcat tomcat) {
            tomcat.enableNaming();
            return super.getTomcatEmbeddedServletContainer(tomcat);
        }

        @Override
        protected void postProcessContext(Context context) {
            ContextResource resource = new ContextResource();
            resource.setName("jdbc/dataSource");
            resource.setType(DataSource.class.getName());
            resource.setProperty("driverClassName", driverClassName);
            resource.setProperty("url", databaseUrl);
            resource.setProperty("password", databaseUsername);
            resource.setProperty("username", databasePassword);
            context.getNamingResources().addResource(resource);
        }
    };
}

@Bean
public DataSource dataSource() throws IllegalArgumentException, NamingException {
    JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
    bean.setJndiName("jdbc/dataSource");
    bean.setLookupOnStartup(true);
    bean.setProxyInterface(DataSource.class);
    bean.setResourceRef(true);
    bean.afterPropertiesSet();
    return (DataSource) bean.getObject();

}
Stacktrace is:

Answer 1

您需要在JndiObjectFactoryBean上将lookupOnStartup设置为false。

或者，如果您需要在启动期间进行查找，那么this answer可能会引起您的兴趣。

编辑：您还错误地在JndiObjectFactory bean上设置了JNDI名称。它必须是java:comp/env/jdbc/myDataSource而不是jdbc/dataSource。

您在查找资源时使用的名称与注册资源时使用的名称不同，因为注册会自动将资源放在java:comp/env/下面。

Answer 2

如果您使用的是春季启动，则不需要所有课程。它已在@EnableAutoConfiguration中配置或 @SpringBootApplication

只需将以下内容放入application.xml文件中的application.xml文件或等效文件

即可

spring.datasource.driverClassName=JDBCDriverClassName
spring.datasource.url=databaseUrl
spring.datasource.username=databaseUsername
spring.datasource.password=databasePassword
spring.datasource.jndi-name=java:jdbc/dataSource

使用嵌入式Tomcat和JNDI进行Spring引导
